Engine hesitation/power problem
In the last couple days, my Ranger has developed a missing/hesitation when accelerating or going uphill when the engine is cold. It has so far cleared up after the engine warms up, but seems to have a little less power than normal. The check engine light came on when this problem began a couple days ago. Up until now, this has been a rock solid vehicle, never given me a moment's worth of trouble. I've faithfully performed normal recommended maintenance on it. Would really like to get to 200k or better before I have something major that needs repair. Any ideas? I can't afford to let a dealer bleed me dry on diagnostics and shot-in-the-dark replacement of parts.
Also, a separate problem: when it shifts up from first into second, there is a small metallic ringing noise. It only happens when upshifting, and only between 1st/2nd.
